"How much caffeine is in chai" has no single answer, because chai is a category, not a tea, and the three common kinds give three very different results. This sits in the caffeine cluster beside the chai guide.

Traditional masala chai (black tea base)

Authentic masala chai is built on a strong black tea, usually robust Assam, simmered with milk and spice, see how to make masala chai and Tea India. Its caffeine is essentially that of a strong black tea, roughly the 40 to 75 mg black tea band from caffeine in black tea, sometimes towards the top because chai is brewed strong by design.

Chai latte (often more, sometimes less)

A cafe or sachet chai latte varies enormously: some use a concentrated black tea base and land high, others are mostly spiced milk and sugar with little tea and land lower, see chai vs chai latte and Drink Me Chai. The answer is "read the product", because the format hides the dose.

Rooibos and caffeine free chai

Rooibos chai or herbal "chai" blends use a caffeine free base and are genuinely zero caffeine, the spice without the stimulant, see Dragonfly Cape Chai Rooibos and the low caffeine list. This is the route for an evening chai or for children.

Why it is brewed strong

Chai is traditionally decocted, simmered hard with milk, which extracts efficiently, so a black based chai tends towards the upper end of the black tea range rather than the lower, the strong brew principle of this cluster applied by the recipe itself.

Practical budgeting

Treat a black based chai as a strong black tea for caffeine purposes; treat a rooibos chai as caffeine free; treat a latte as "depends, check it". In pregnancy mind the black based versions, see is black tea safe in pregnancy and the caffeine guide.

Bottom line

Chai caffeine is a question about which chai: black based masala chai is strong black territory, a latte is anywhere, a rooibos chai is none. The spice carries no caffeine; the base decides everything.

Chai caffeine, in one place

Kind of chai	Base	Caffeine
Traditional masala chai	strong black, usually robust Assam	black tea territory, often the upper end (~40 to 75mg+)
Cafe or sachet chai latte	concentrate or syrup, variable tea	anywhere, depends entirely on the product
Decaf chai	decaffeinated black	low, not truly zero
Rooibos or herbal chai	caffeine free base	none

Budgeting the caffeine

General guidance puts a sensible daily ceiling around 400mg for most adults and about 200mg in pregnancy, from all sources combined, so a black based chai counts as a strong black tea against that, a rooibos chai as effectively free, and a latte as a wildcard until the label says otherwise. The black base also carries L theanine, which tends to make the same dose feel calmer and more sustained than coffee. A shorter, gentler brew is a genuine lever for less. This is general information, not medical advice.
